I think I can answer this. There is a CD that shows up on eBay and some of the other auction sites that is a combination of Motion Picture and an album called SITA D which they claim to be a Boris Blank album. (see image below)
This is a bootleg CD and Sita D has nothing to do with Boris Blank or Yello.
But there is good news. The Sita D album is a legitimate album but it is the music of the group "Black Star Liner" the particular album that these supposedly Boris Blank tracks come from is "Bengali Bantam Youth Experience!" the good news is this is a pretty good album and does have a Yello sound. The music comes from India.
